Abstract: A photobleachable ink composition having: at least one light-sensitive optical-state change material; at least one bleaching accelerant; at least one solvent; and at least one binder material; wherein the ink composition has a viscosity between about 0.1 centipoise and about 10,000 centipoise, and a maximum optical absorbance in a range from about 200 nanometers to about 800 nanometers; and wherein the ink composition is capable of change from a first optical state to a second optical state upon exposure to light. The composition may also include a plasticizer.

Abstract: A system provides a multi-sided media viewer capable of displaying media assets from an electronic archival news and content database. Each side of the media player contains different information regarding the media asset. A primary side of the media asset may display a media asset related to an educational program, such as a course curriculum or the like. The secondary sides of the media viewer may contain additional information regarding that media asset, including personalized information generated by a system user as well as automatically populated information, such as information collected from other external news services or content providers. The system may further provide an educational game in which users are encouraged to find and draw connections between media assets to create an interconnection of related news items.
